I get that message after playing a game/movie for about 5 minutes at the most. If its a game it will freeze it for a second give me that message and change my screen resolution to whatever my game resolution was at. then i can keep playing with game with no errors after...

But while playing Movies it gives me the message and sometimes reboots my PC on its own. The times it doesnt boot my PC it says no signal on my PC for couple of seconds then give me that message.. the fan speed increase dramatically and it gets loud right when this happens and then it goes back down when the message pops up..

I tried flashing it to different bios and have tried different drivers but still no luck. It supposely be a X1900XTX, but just in case I even flashed it to a XT version and still dont work. Does anyone know *** is going on??

Temps are fine, I watch them while playing games/movies and they dont go over 57 celcius. However... my CPU temps are kinda high (in 50's) can that be causing a problem like this?

ATI experts please help me out here as I beent rying to solve this since last 3 days. Thanks in ddvance.

If it's overclocked, drop it back down to stock and see what happens. Normally I get that when the fan cooler is clogged and it overheats. There is still a chance its a heat problem, have you ever redone the Thermal Paste?

I'm still running on stock cooler with exceptional airflow in the case, aftermarket coolers are great. Change the ATI Tool to monitor temps every sec instead of 10 seconds.
You temps are probably spiking at the last moment before VPU recover kicks in and its not getting logged due to shutdown.
You may be suprised at the ammount of dust and debrise inside that cooler. Don't take it apart unless you have thermal paste on hand, your gonna need to replace it.

I have the Arctic Silver 5 (one used for cpu's) that sould work fine right?

And I'm using GPU-Z to monitor temp... It refreshes pretty fast, I think its at 1sec refresh too.

The x1900XTX is an incredibly hot card. I think taking the card out and taking the cooler off, cleaning the thermal paste that was on it (the card and the cooler, clean both), clean the dust out of the cooler (can of air works well), and apply some good thermal paste to it should cure you. AS5 is conductive, so if you aren't confident in your abilities, you can use AS Ceramique or Arctic Cooling MX-1 (or 2).

Your CPU temp shouldn't cause a VPU recover. If you mean 50c IDLE on the cpu, that is a problem in it's own right, re-seat the cooler and re-apply thermal paste (again cleaning the old stuff).

Just uninstalled all the drivers again and defragmenting now.. seems like gonna take a while... even thoug only 20 gig used

Also you should have Defragmented after driver removal and before install of new drivers. ATi drivers leave "reference points" behind on the HDD after removal. It is necessary to remove these reference points before installing new drivers to avoid coruption.

Hope it works this time, ATI drivers get realy corrupted when overwritten and not removed and cleaned out properly.

I didn't mean to "use" it to unistall, I ment to use ADD/REMOVE and REMOVE it also.

EDIT: Defragmenting is going on as well right now. My har drive is screaming LOUDLY. i need a new drive

Ok. I removed the ATI uninstall utility and everything else related to ATI. But just to be on safe side I will use Driver Cleaner Pro and delete anything relating to ATI that I see on it. Then restart and then install new drivers.

Sounds better, before INstalling new drivers - ONLY Defrag will remove the reference points.

Didnt help... same damn problem... Temps are well under control too...

mannn i'm close to giving up on damn ati...

anymore ideas/suggestions??

It could be a Bad BIOS flash, but normally when this happens the card doesn't even run.

It could be the card is dying.

It could be your PSU. Even though it powered the card before you were probably maxing it out. Now it has aged enough and can no longer support the card.

You power supply is probably on its last leg.

I could not even boot my X1900XTX with a Neo550. Had to get a 650 watt Enermax to boot
my PC with that card.

The only other choice other than this would be the drivers again. It is possable. ATI drivers are very picky and easy to corrupt. I would say try the drivers one more time.

Remove old drivers and "unistaller tool" with Add/Remove programs
Run a windows "Search:" for ATI and delete all drivers found.
Defragment HDD
Reboot PC
Install new drivers from ATI site.
Reboot and try again.

If doing this Step by step as described does not solve it either the card is dying or the PSU is on its way out.
